Dipyridamole Injection is a coronary vasodilator used as an alternative to exercise in thallium myocardial perfusion imaging for the evaluation of coronary artery disease in patients who cannot exercise adequately. Dipyridamole injection is available in generic form. Common side effects of dipyridamole injection include:
- chest pain/angina pectoris
- electrocardiographic changes
- low or high blood pressure (hypotension or hypertension)
- shortness of breath
- numbness and tingling, or
The dose of dipyridamole injection as an adjunct to thallium myocardial perfusion imaging should be adjusted according to the weight of the patient. The recommended dose is 0.142 mg/kg/minute (0.57 mg/kg total) infused over 4 minutes. Dipyridamole may interact with theophylline and other xanthine derivatives such as caffeine, or cholinesterase inhibitors. Tell your doctor all medications and supplements you use. During pregnancy, dipyridamole should be used only if prescribed. This drug passes into breast milk. Consult your doctor before breastfeeding. /p>

Adverse reaction information concerning intravenous dipyridamole is derived from a study of 3911 patients in which intravenous dipyridamole was used as an adjunct to thallium myocardial perfusion imaging and from spontaneous reports of adverse reactions and the published literature.
Serious adverse events (cardiac death, fatal and non-fatal myocardial infarction, ventricular fibrillation, asystole, sinus node arrest, symptomatic ventricular tachycardia, stroke, transient cerebral ischemia, seizures, anaphylactoid reaction and bronchospasm) are described above (see WARNINGS).
In the study of 3911 patients, the most frequent adverse reactions were: chest pain/angina pectoris (19.7%), electrocar-diographic changes (most commonly ST-T changes)(15.9%), headache (12.2%), and dizziness (11.8%).
Adverse reactions occurring in greater than 1% of the patients in the study are shown in the following table:
|Incidence (%) of Drug-Related Adverse Events|
|Chest pain/angina pectoris||19.7|
|Electrocardiographic Abnormalities/ST-T changes||7.5|
|Blood Pressure Lability||1.6|
